P&ID data extraction to Excel
A P&ID carries an equipment list, a line list, an instrument index and a valve list — all drawn rather than tabulated. AxioExtract reads the sheet into those four tables so they can be reviewed against the drawing and exported as spreadsheet rows.

Why P&IDs use a frontier vision model
Process diagrams depend on spatial relationships: which instrument sits on which line, which valve belongs to which loop, and which tag applies to which piece of equipment. Cheap models read the characters but lose those relationships, so P&IDs are routed to a frontier vision model. That is reflected in the rate of 8 credits per page. Invoices and plain tables use a much cheaper chain — see supported formats for every rate.
Large sheets are read in tiles with a coordinate grid overlaid, which keeps dense tag clusters legible instead of averaging them into one unreadable page.
Reviewing a P&ID read
Selecting a row highlights where that value appears on the drawing, so an instrument index of several hundred tags can be checked without hunting across the sheet. Low-confidence readings are flagged, and any region can be boxed and re-read. Export happens after review, to Excel, Google Sheets, JSON or XML.
A worked example
Take a single process sheet showing two pumps, a filter, three control loops and a dozen lines. The equipment table comes back with the pump and filter tags, their descriptions and any printed duty data. The line table lists each line number with size, service and specification. The instrument table lists the loop tags with their type and service, and the valve table lists valve tags with type and size. Four tables, each ready to paste into an equipment list, line list, instrument index or valve schedule.
Selecting any row highlights where that value was read on the sheet, so a tag that looks odd can be checked in a second rather than hunted for. Low-confidence readings are flagged, and any region of the drawing can be boxed and re-read on its own.
Marking up a set of drawings
P&IDs rarely arrive alone. Sheets can be uploaded as a batch and each is read against the same schema, so the tables append cleanly into one workbook — the point at which a tag register or an instrument index actually becomes useful.
